4 Claims.

This invention relates to hair dressing and has Y special reference to apermanent wave curler.

One important object of the invention' is to provide a novely device ofthis kind having improvedmeans for grasping a tress of hair.

A second important object of this invention is to provide an improvedcurl forming device for such a curler.

A third important object of the invention is to provide a novelarrangement oi' tress grasping device or clamp and'curler arranged fordetachable interlocking engagement, after the hair has been wound on therod.

With the above and other objects in view, the inventionA consists ingeneral of certain novel details of construction and combination ofparts hereinafter fully described, illustrated in the accompany drawing,and specifically claimed.

In the accompanying drawing, like characters of reference indicate likeparts in the several views, and

Figure 1 is aside elevation of the tress clamp or base and rod assembledwith the rod clamp opened.

Figure 2 is a side elevation of the same parts atv right angles toFigure 1 and with the hair e wound on the rod.

Figure 3 is a View of the opposite side of Figure 2 with the wrapperapplied.

Figure 4 is a horizontal sectional view on the line 4--4 of Figure l..

Figure 5 is a vertical section on the line 5 5 of Figure 4.

Figure 6 is an elevation of the device completely assembled, ready forapplication of the heating unit.

Figure 7 is a vertical section on the line 'I-l of Figure 4, certainparts being shown in elevation.

Figure 8 is a horizontal section on the line 8--8 of Figure 6.

In the embodiment of the invention here disclosed there is provided abase member or tress,

clamp which consists of 'upper and lower 'plates Iii preferably made ofaluminum or other light metal which are each provided with a notch Iiextending inwardly from one edge to about the center of the plate. Atthe opposite sides from the notches these plates are held in properspaced 50 relation by a spacer I2 which is preferably made of bakeliteor other similar material. 'I'his spacer extends to the inner ends ofthe notches and the edge at these notches is provided with a padding II3 of felt or the like. The notches II bifurcate 55 the plates I0 andbetween the arms of the bifur- 1934, Serial No. 717,517 (Cl. 132-33)cations at one side of said notches there is pivoted one end of a clampplate I4 having its inner edge provided with a padding I 5 similar tothe padding I3. The other or free end of this clamp member I4 slides inand out between the bifurcations on 5 the remaining side of the notches.The free end of the clamp member I4 is provided with a slot I6 whereinis pivoted one end of a link I'I which can swing in and out of this slotand, when the clamp is closed, in and out of a similar slot in thecorresponding end of the spacer I2 and when the clamp is closed and thelink I'I in the slots the free end of this link projects beyond the rearedge of the spacer I2.` To the free end of the link I'I there is pivoteda cam I8 having an operating 10 handle or linger piece I9. As shown bestln Figure 5, the clamp I4 may be opened by swinging the handle I9 fromits full line position in that gure in a clockwise direction, thenswinging the link Il in a similar direction and finally swinging theclamp I4 to open the notches, the parts being shown in full lineposition in that figure and partly open in broken lines. The undersideof this base is provided with a felt pad 20 and in this base is provideda circular opening 2I located adjacent the inner ends of the notches IIand across this opening extends a bar or key 22.

In connection with this base, certain winding mechanism is used. whichconsists of a cylindrical rod 23 whereon is mounted, for rotation, asleeve 24, the said rod being of greater diameter at one end, to providea head 23m, and having im other end reduced and screw-threaded as shownat 23h to receive a wing nut 25. One end of the sleeve 24 rests upon theshoulder formed by the inner end of the head 23a. and its other end isadapted to be engaged by the wing nut 25, whereby it may be clampedagainst rotation, between said nut and head. To the upper end portion ofthis sleeve 2t is pivoted a clamping finger 26 of arcuate crosssectionand, when in normal position, this nger extends down alongside of thesleeve and partly encircling the same. The head 23a is of a size to litwithin the opening ZI and its outer end face is provided with a groove2'I, to receive the crossbar or key 22. The upper end of the sleeve 24is provided with a suitable nger grip here shown in the form of abutterfly nut, although any form oi' linger grip that may be founddesirable may be used.

There is also provided, for use with this invention, .the usual wrappersor flannels 29 and a perforated covering tube 30. Those skilled in theart will understand that such annel wrappers are generally moistenedwith water or a suitable setting liquid before application. On the lowerend of the covering tube 30 there is provided an oppositely disposedpair o1' locking hooks 3| adapted to engage, by twisting movement of thetube, a pair of headed studs 32 projecting upwardlypfrom the base.

In using this invention the operator separates a tress of hair coveringabout one square inch from the remainder of the hair on the scalp. Thebase clamp is opened and this tress is inserted in the notches Il afterwhich the base clamp is closed, the base being pushed down close to thescalp. The rod, with the nut 25 loosened, is now taken and its clampingnger 26 opened so that the free end of the tress may be inserted betweenthe sleeve 24 and said clamping nger close to the joint of the latter.Upon depressing the clamping iinger and holding it thus, the end of thetress is gripped rmly between the finger and sleeve. The sleeve 24 isnow rotated to wind the tress from tip to close to the clamp onto thesleeve, the windings Wrapping around the clamping nger to hold it inposition to clamp the tip of the tress. When all of the tress above thebase has been wound in this manner the lower end of the head 23a isinserted in the opening 2l with the key 22 in the groove 21. The sleeve24 is then rotated until any slack in the tress is wound tightlythereon, whereupon the nut 25 is tightened to clamp the sleeve betweenit and the inner side of the head 23a, thus holding the sleeve againstrotation. The tight wrapping of the tress prevents dislodgement of thehead 23a from the opening 2| of the base. The flannel wrapper is nowplaced around the rod and the hair wound thereon, and the perforatedtube is slipped over the wrapper and turned to cause the hooks 3| toengage the studs 32. 'Ihe device is now ready for the application of theheater element which may be of any desired kind and which is not deemednecessary here to be shown as such heater elements are old andwell-known and form no part of the present invention.

There has thus been provided a simple and efcient device of the kinddescribed and for the purpose specified.

It is obvious that changes may be made in the form, proportions, andconstruction of the invention from what has herein been shown anddescribed and that such changes may be made without departing from thespirit of the invention. The invention is, therefore, not to berestricted to the exact form herein set forth but l is limited only bythe scope as claimed.

What is claimed is:

1. A permanent wave device including a base having means for clamping atress, a rod detachably connected to the base, a sleeve rotatablymounted on the rod, a tress clamp carried by the sleeve, and meanscarried 'by the rod for locking the sleeve to the rod at times.

2. A permanent wave device including a. base having means for clamping atress, a rod detachably connected to the base, a shoulder on the 'rod, asleeve loosely encircling the rod with an end engaging said shoulder,means for clamping the sleeve against the shoulder to prevent rotationof said sleeve and a tress clamp carried by the sleeve.

3. A permanent wave device including a base having means for clamping atress, a rod removably mounted in the base, a shoulder on the,

rod, a sleeve loosely encircling the rod with an end engaging saidshoulder, a nut threaded on the rod and adapted to engage the other endof the sleeve, and a tress clamp carried by the sleeve.

4. A permanent wave device including a base member provided with a tressclamp, a rod having a grooved end, said base member having an openingtherein to receive the grooved end of the rod, a bar extending acrosssaid opening to be engaged in said groove whereby to hold the rodagainst rotation, a sleeve loosely encircling the rod, means forclamping the sleeve to the rod, and a tress clamp carried by the sleeve.
